Probably don't want to hear this, but wipe and start over. Maybe even upgrade to Win 7. Probably not an option, but what can I say. Looks like you've done it all and are now grasping for straws. I understand that many folks are still wedded to old OSes because of cost, etc, but if you can afford a bunch of games you can afford to replace your OS eventually. Maybe wait til Win 8 comes out (but I really don't like that Metro interface for a desktop computer, not one bit)
